yes and no. there are some conditions that you are in a hypnotized state and are not aware of conciseness or self awareness but can respond to surrounding stimuli, but you will not have the addiction of eating human flesh.
A zombie is a mythological creature and, as such, is not caused by any disease.
yea its called sleepwalking
Grow it like any zombie.
Actually there are zombies but not the thing your thinking of ur not actually eating people or dead you have a disease that is very contagious and the slightest touch can give u that but luckily there is a vaccine to the harmful disease
Nope, they aren't real. Though there is a disease that can make you act like a zombie. Many people who suffer from this disease think of meat, and will go an a rampage if they do not get their desired food.
No. Because the zombie disease takes away your free will. Without a free will you can't express yourself. When you moan and groan your expressing yourself
Grow "neglect" dreads, a beard, paint your face like a zombie
It is possible, but it wont necessarily be like what is in movies. it would be the spread of disease, death, insanity, and cannibalism. It wont be like the living dead, but just diseased people.
It's a rage disease that turns people into cannibals and makes them go insane.
A zombie invasion is just an outbreak of zombies like a takeover
No, zombies are mythical and not a real risk. Might as well worry about unicorn stampedes. Not until somebody bombs us hard like a nuclear holocaust. Yes, there actually is because of cannibalism disease of such.
You just get a sackbot, make it look like a zombie and then lethalise it. Use a emitter to make a zombie survival with weapons.
